Heat kernel recurrence on space forms and applications
Chengjie Yu, Feifei Zhao
In this paper, we first give a direct proof for two recurrence relations of the heat kernels for hyperbolic spaces in \cite{DM}. Then, by similar computation, we give two similar r…
Affine Self-similar solutions of the affine curve shortening flow I: The degenerate case
Chengjie Yu, Feifei Zhao
In this paper, we consider affine self-similar solutions for the affine curve shortening flow in the Euclidean plane. We obtain the equations of all affine self-similar solutions u…
On the Li-Yau type gradient estimate of Li and Xu
Zhigang Chen, Chengjie Yu, Feifei Zhao
In this paper, we obtain a Li-Yau type gradient estimate with time dependent parameter for positive solutions of the heat equation, so that the Li-Yau type gradient estimate of Li-…
A note on Li-Yau type gradient estimate
Chengjie Yu, Feifei Zhao
In this paper, we obtain Li-Yau type gradient estimates with time dependent parameter for positive solutions of the heat equation that are different with the estimates by Li-Xu \ci…
